The Firefly is the world's first, electric, car for 5 to 10 year old kids and “handles and drives” like a full-size counterpart, Young Driver Motor Cars Limited said. Junior Mode limits the maximum speed to five miles per-hour and optional sensors ensure it automatically stops if a child is likely to hit (say) a park bench.

Experienced Mode increases the maximum velocity to 10 miles per-hour, then switches-off the sensors that bring it to a halt. Furthermore, the car can – in either setting – be stopped by an adult via remote control if the child is dangerous, careless or disobedient. Maximum range is around 120 metres.

Furthermore, Firefly brakes, throttle and forward and reverse controls operate via hydraulics. Such systems complement the: independent suspension, adjustable driver seat, fixed passenger seat, indicators, LED head/tail lights, twin electric motors and the nine-hour continual runtime (up to). The speed, time, and power reserve are confirmed by a tablet-style interface on the dashboard.
